Description

Conductivity type structure for preventing tube explosion of filtering equipment

Technical Field

The utility model relates to the technical field of filtering equipment, in particular to a conductive structure for preventing the explosion of the filtering equipment.

Background

In the experimental process, the bag filter element is usually matched with a hose, namely, a liquid inlet port of the filter element is connected with the hose, and a peristaltic pump is used for pumping the solution into the filter element along the hose. In order to save the experiment cost, the filter element can be reused, and although the filter element is washed by purified water after each use, the filter element is soaked in 0.1M NaOH solution for storage to avoid bacterial growth, and is washed again by the purified water when the filter element is used next time, the filter element still has plugs which cannot be washed cleanly. The blockage can cause excessive internal pressure of the filter element in use, so that a liquid inlet port of the filter element is separated from a hose, and the condition of pipe explosion occurs, especially when protein products and acid/alkaline solution are filtered, if pipe explosion accidents occur, biological pollution and harm of alkaline solution corrosion burn human bodies are easy to occur.

Two groups of opposite conductive metal sheets and contacts are arranged, the distance between the first metal sheet and the first contact is smaller than the distance between the second metal sheet and the second contact, and when the inner ring is close to the outer ring, the first metal sheet is contacted with the first contact first. Because the inner ring is close to the outer ring due to the pressure generated at the joint of the liquid inlet of the filter element and the guide pipe, when the pressure is smaller, only the first metal sheet is contacted with the first contact, and after the pressure is larger, the second metal sheet is contacted with the second contact. Through the controller, when different sheetmetals and contact, control different suggestion modules and carry out the suggestion, when only first sheetmetal and first contact, control first suggestion module carries out the suggestion, and after second sheetmetal and second contact, control second suggestion module carries out the suggestion to realize carrying out the suggestion with different modes in different pressure ranges, make the staff know current pressure range more clearly, whether need change the filter core.

Further, the first prompting module is a yellow lamp, and the second prompting module is a red lamp.

When the pressure is smaller, the prompting is carried out through a yellow lamp, and when the pressure is larger, the prompting is carried out through a red lamp.

Further, the intelligent alarm device also comprises a power supply module, wherein the power supply module is used for supplying power to the control circuit and the prompt module.

A power supply is provided.

Further, the inner ring is made of flexible materials, and the outer ring is made of hard materials.

The inner ring is pressed to approach the outer ring, so that the outer ring is fixed by adopting a flexible material, and the outer ring is made of a hard material.
